Prospective evaluation of adnexal masses with endovaginal gray-scale and duplex and color Doppler US: correlation with pathologic findings.

Abstract

Because there is an overlap in the resistive index (RI) values of benign and malignant masses, RI values alone cannot be relied on. Combining the detailed analysis of internal architectural appearance with the flow velocity patterns obtained at pulsed Doppler US increases the specificity in the diagnosis of adnexal masses.
